Got a work intranet application that works fine in IE6 but doesn't like IE7? Amazingly, Microsoft has provided a way to install the non-Vista-compatible IE6 on Vista. Well, maybe not quite, but near enough...
Internet Explorer 7 has been out for quite a while now, yet there are still plenty of sites out there that can’t cope with it, and demand that users connect using IE6. Unfortunately, most people (certainly the vast majority of home users) are running IE7, having received it as part of a Windows XP update, or they’re running Windows Vista which uses IE7 by default.
If you’re running Windows XP, you can roll back to IE6, but this seems rather a shame to do. If you’re running Windows Vista, there’s no rollback option since IE6 was never released for Vista.
What you can do instead is make use of Microsoft’s Internet Explorer Application Compatibility VPC Image. These are two virtual PC hard drive images (downloadable here) which contain a full, pre-activated copy of Windows XP SP2 – one contains IE6 and the other IE7. The idea is to make users able to test either application, and to this end each image contains the IE7 Readiness Toolkit, the Script Debugger and the IE Developer Toolbar.
Free, free, free: a pre-activated copy of Windows XP SP2 in a downloadable virtual machine, complete with IE6.
The individual downloads are fairly chunky (443MB and 491MB respectively) and expand out to 1.48GB and 1.58GB VHD files. To use the files, you need to install Virtual PC 2007, create a new machine using the default settings, and then go into each virtual machine and point the hard drive to the VHD file you just downloaded. Make sure the other settings are correct (especially networking) and then start the machines from the console.

And the IE7 virtual machine: for those sado-masochists who are sticking with IE6 but want to dabble in IE7.
The VHD files don’t have an unlimited life – the current set are due to expire in about a month on the 17th of August 2007 - but it seems that Microsoft has been releasing updated images over time, so as long as there’s a need for them to keep IE6 developers happy, the images should be available for some time.
We've put in an enquiry with Microsoft's PR people to find out whether Microsoft plans to extend the date again.
The deadline: will Microsoft kill off IE6 once and for all, or will it extend the deadline of its free virtual machine? (We're hoping for the latter!)
